Filed: 1917-04-13
Abstract: 108,442. Bailey, J. C., and Brindley, J. E. April 13, 1917. Printing in several colours; transfers.-A transfer for decorating pottery or earthenware, or for other purposes is produced by transferring prints to a zinc plate previously coated with wax, attach. ing a sheet of transfer paper to the print by means of a gumming solution composed of white dextrine, glycerine, ox-gall, and water, and then detaching the transfer by heating the zinc plate preferably by the direct application of steam to the back of the plate. The prints are obtained and transferred to the zinc plate in the following manner. From a key plate etched or engraved with the full design and with fitting or registering circles or marks outside of the design, part design plates for the different colours are prepared by taking the various part design impressions with the fitting circles from the key plate and transferring to copper plates which are then engraved. Prints are taken in the corresponding colours from these plates on to paper sheets and these prints are transferred in succession to the prepared zinc plates. The first print is transferred in its entirety, but with the succeeding prints the fitting circles are partially cut away so that the parts remaining can be exactly superposed on the fitting circles transferred by the first print. When dry this multicolour print is coated with gum and is then ready to receive the transfer paper.

Patent GB-319182-A (GB)
Title: Improvements in or relating to process and apparatus for rolling plate glass
IPC: C03B13/02
Filed: 1929-02-19
Abstract: 319,182. White, A. E., (Pittsburg Plate Glass Co.). Feb. 19, 1929. Rolling.-Relates to apparatus for making plate glass in which a body of glass is poured into the pocket between parallel rollers and is prevented from spreading sideways by means of metal plates which fit into the pocket between the rollers. The invention consists in causing the glass to adhere to these end plates as it is found that such adhesion causes the rolled plates or strips to have smoother edges. Fig. 5 shows an apparatus of the kind described in Specification 269,300 in which a mass of glass is rolled between a small roller 3 and the surface of a large shell or drum 1. The pocket into which the glass is poured is defined by end plates 7, Fig. 3, that fit into the space between the roller and the drum. Steel plates 8, formed with spikes 11, are removably attached to the plates 7 by means of brackets 10. In operation, the plates 8 are made red hot in a separate furnace and are then placed in position on the plates 7. A body A of glass is poured into the pocket and adheres to the spiked inner surfaces of the hot plates 8. The adhesion holds back the glass at the sides of the pocket, and it is found that the feed of the glass between the rolls is more uniform and steady. The plates 8 are so proportioned that when they are hung on to the plates 7, their lower curved edges 12 are separated from the surface of the drum 1 by a space which is greatest at the front end 13, Fig. 5, and decreases gradually until the plates touch the surface of the drum. Instead of being spiked, the plate may be formed with perforations which taper inwards.
